I'm trying to read a text file in Python and I receive this error, the file is saved in the same directory as the current python file. How can I resolve this error?

import smtplib

import time

import imaplib

import email

def read_email_from('mbox.txt',"r"):

try:

mail = imaplib.IMAP4_SSL(SMTP_SERVER)

mail.login(FROM_EMAIL,FROM_PWD)

mail.select('inbox')

type, data = mail.search(None, 'ALL')

mail_ids = data[0]

id_list = mail_ids.split()

first_email_id = int(id_list[0])

latest_email_id = int(id_list[-1])

for i in range(latest_email_id,first_email_id, -1):

typ, data = mail.fetch(i, '(RFC822)' )

for response_part in data:

if isinstance(response_part, tuple):

msg = email.message_from_string(response_part[1])

email_subject = msg['subject']

email_from = msg['from']

print 'From : ' + email_from + ' '

print 'Subject : ' + email_subject + ' '

except Exception, e:

print str(e)
